Dr. Battery 3ICP6/55/90 for ThinkPad P40 Yoga

This replacement battery is built for Lenovo ThinkPad P40 Yoga and ThinkPad Yoga 460 series laptops. It uses Li-polymer cells rated at 11.4V and 3600 mAh to restore mobile runtime. The pack fits the original chassis dimensions of 8.0x1.5x0.8 cm and weighs 0.4 kg. Safety circuitry guards against over-charge, over-discharge, overheating and short-circuit.

Sustained-load behaviour with Li-polymer cells

The Li-polymer chemistry maintains stable voltage during extended work sessions rather than sagging after a short burst. Integrated protection circuits continuously monitor temperature and current to prevent thermal throttling or sudden shutdown under load. OEM-grade cells are selected for consistent discharge curves across the full capacity range. This design supports reliable daily use for business professionals and mobile users.

Upgrade path from worn or failed original packs

This unit replaces Lenovo part numbers 00HW020, 00HW021, SB10F46458 and SB10F46459 when the original battery no longer holds charge. The jump is worth it when runtime has dropped below usable levels or the system reports a permanent failure. Buyers who need a different voltage or form factor should verify the part number before ordering. The Professional Series targets the same fit and electrical specification as the factory pack.

Questions about this item

How hot does the 11.4V 3600mAh Li-polymer battery run during a full day of use?

The pack uses OEM-grade Li-polymer cells and built-in circuitry that guards against overheating, over-charge and short-circuit, keeping temperatures within safe limits under normal workloads.

Does my ThinkPad P40 Yoga or Yoga 460 need any extra cable or adapter to fit the 8.0×1.5×0.8 cm battery?

No extra parts are required; the battery is a direct replacement for Lenovo part numbers 00HW020, 00HW021, SB10F46458 and SB10F46459 and slots into the existing compartment.

Will the 0.4 kg replacement work reliably in a 20FY-series Yoga 14 that originally shipped with a different capacity pack?

Yes, the Professional Series cell chemistry and protection circuit are matched to the 11.4V rail used across the P40 Yoga, Yoga 460 and 20FY Yoga 14 lines, so the system recognises and charges it normally.
